Abstract

To enrich the sensing mechanism of the FBG sensors, the cantilever FBG sensor is taken as an example to analyze the effect of the deflection on the embedded stress distribution and structure parameters of the FBG, and a widely applicable analysis method is thus proposed. Models of the single-core and multi-core FBG sensor are built by the proposed method and a modified transmission matrix method is utilized to simulate the built models. The lateral resolution of the multicore FBG sensor is proved to be 1500 times higher than the single-core FBG sensor. Simulation results of the proposed models indicate that this approach is tally with the experiment of other researches, and it can be used to analyze the performance of the designed sensors, such as spectrum signal and resolution, or as a guide of designing FBG sensors.
